A look at the Potential Benefits of Anti Estrogens

Estrogen, also known as oestrogen, is a steroidal hormone that plays a major role in the regulation of a woman’s sexual reproductive system. It is also present in men where it plays roles in the support of sexual function and in fat and muscle mass retention.


In men, estrogens are known to play a role in gonadotropin feedback mechanisms, bone maturation and resorption, brain function, and in the metabolism of lipids [1]. As one ages there is a natural decline in testosterone production (starting at the age of 30 but increasing rapidly in those over the age of 50) [2] and this can lead to an imbalance of sex hormones such as testosterone and the estrogens.  Some other major reasons for lowered testosterone production include being overweight, stress, and certain medications.

This loss of testosterone balance may lead to losses in libido, feelings of fatigue, and a lowering in the amounts of sperm a man is able to produce.

Like with testosterone, the estrogen hormone plays a role in whole body anabolism in men. Estradiol is the primary active estrogen in a man. The use of estrogen blockers in men may help to support hormonal imbalances that can occur when their testosterone levels decrease.

The blocking of estrogen has been reported to lower estradiol and to increase FSH, LH concentrations in the serum [3]. Further to this, high levels of estrogen in men caused by imbalances are reported to increase the amount of breast tissue, reduce muscle mass, affect mood, and to interfere with blood glucose homeostasis.

The reduction of muscle mass associated with increased estrogen levels is of especial importance to people who are into working out at the gym to increase muscle strength, those involved in explosive sports, or those who partake in bodybuilding.

The blocking of the main enzyme involved in estrogen biosynthesis (the synthetase Aromatase) is able to affect production of the potent estrogen estradiol from testosterone and estrone [4]. Increased estrogen levels are reported to be associated with increases in water retention and subcutaneous body fat [5].


In women, estrogen plays a major role in the reproductive system. They are present at much greater quantities in women than they are in men, and play a key role in controlling the menstrual cycle and in the development of secondary sexual characteristics such as breasts.

The female body undergoes an array of hormonal changes during the menopause, and this can lead to an imbalance in estrogen levels [6]. Having an excessive amount of estrogen is known as estrogen dominance. Some of the things association with estrogen imbalance include tender breasts, weight gain, feeling bloated, loss of hair, tiredness, trouble sleeping, mood swings, lack of sex drive, irregular menstruation, and cognitive issues.

The VitaMonk anti-estrogen product EstroTrax contains the following carefully selected ingredients that are thought to help support healthier levels of estrogen: Boron glycinate; Calcium; Diindolylmethane; Grape seed extract; Stinging nettle root; Tongkat Ali Powder; Trans-resveratrol; and Zinc.

Grape Seed Extract (GSE)

Grape seed extracts are rich in proanthocyanidins and catechins [7]. Once consumed the procyanidins found in GSE are metabolized into catechins in the body.

The use of Grape seed extract has been reported to inhibit Aromatase [8]. This enzyme catalyzes androgen to estrogen and hence its inhibition directly affects the production of estrogen in the body. It is also reported to be associated with decreased estrogen synthesis and increased amounts of androgen precursors in postmenopausal women [9].

Stinging Nettle Root

The stinging nettle (Urtica dioica) is an herb that has traditional use in the support of male health. It is thought to support the inflammatory response and has been reported to support healthy testosterone levels in rats [10].

It may have an indirect effect upon estrogen and androgen levels through being able to interfere with Sex-Hormone binding globulin [11].

Diindolylmethane (DIM)

Diindolylmethane is a derivative of Indole-3-Carbinol (I3C), which is found naturally in leafy vegetables belonging to the Brassica genus [12].

This molecule is able to indirectly activate estrogen receptors via activation of the PKA protein [13]. Diindolylmethane can also convert estrogen steroids into new forms of metabolites, thus lowering the overall presence of estrogens [14].

Tongkat Ali Powder

Also known as Eurycoma Longifolia Jack, the Tongkat Ali herb has long been used as a general tonic in the traditional medicines of SE Asia. It is reported to have aphrodisiac effects and to support sperm health [15].

It contains two quassinoids that have been reported to have potent anti estrogenic effects [16]. These effects are likely to be beneficial for sperm health and motility [17].


The resveratrol flavonoid is naturally found in wine and is reported to support cardiovascular health and to have nootropic properties [18].

It has a similar structure to the estrogen molecule and may have competitive aspects metabolically as it has been reported to be able to affect processes involving aromatase and affect the conversion of estrogen from testosterone [19].

Boron Glycinate

Boron is a mineral that is naturally present in fruits and vegetables. It is reportedly able to have beneficial effects upon both testosterone and estrogen levels. It may help to increase free testosterone levels without affecting overall testosterone levels [20].

The same research work also put forward that serum estradiol levels could be reduced in adult men taking 10 mg of Boron on a daily basis for one week [20].

Minerals (Zinc and Calcium)

These two minerals have both been reported to have an effect upon estrogen and/or testosterone.

Supplementation of zinc may help to reduce estrogen levels through its ability to act as an aromatase inhibitor [21].

Black Pepper Extract

Black pepper contains a molecule called piperine. This helps to prolong how long exogenous materials such as nutritional supplements can stay in the body and remain bioactive [22]. It does this through inhibiting enzymes involved in the body’s waste disposal mechanisms.

What foods can block estrogen?

You may wish to include foods that are rich in DIM in your diet; these include cruciferous vegetables such as Kale, Sprouts, Artichokes, Bok Choy and cabbage. Other potential estrogen blocking or testosterone promoting foods include mushrooms, red wine /grapes, oats, onions, citrus fruits, coconut oil and garlic.

Which foods should I Avoid? What foods are high in estrogen?

Foods known to be rich in phytoestrogens include sesame and flax seeds; legumes, citrus fruits such as oranges, peaches, and apricots; Soy (miso, tofu soya milk etc.); olives, chick peas, and root vegetables such as yam and carrots. Be aware that many animal products may also contain large amounts of estrogens due to being fed on hormone rich diets. Ideally try to purchase and eat grass fed meats.

Do eggs have estrogen in them?

Eggs contain phytoestrogens. These are found largely in the yolks. That said the levels are very low compared with other foods (about 120 times less than found in soy for example). You may wish to eat free-range eggs and avoid eggs produced from chickens that have been fed synthetic estrogen feeds.

Do bananas have estrogen in them?

As bananas contain members of the bromelain enzyme group and are rich in potassium they are more known for their testosterone boosting properties.

What is an anti estrogen supplement?

Antiestrogen products such as VitaMonk EstroTrax are designed to help support healthy levels of estrogen production. Lowering the amount of estrogen production can also help to support healthier levels of testosterone in men and may help to support many aspects of the menopause in women.

What will block estrogen / How does an anti estrogen work?

Most anti estrogens work by blocking the enzyme aromatase, which is involved in catalyzes of testosterone into estrogens.

What is the best estrogen blocker?

The ingredients in VitaMonk EstroTraxTM have been carefully selected for their potential roles in promoting healthy levels of estrogen and testosterone. As we source only the highest quality ingredients on the market we feel that we offer one of the best anti estrogen products available for sale.

How can men reduce estrogen?
